Borrowing Base vs Credit Limit: Reconcile Business Availability
Model eligible receivables and inventory separately from sales forecasts before deciding what a monitored facility can fund.
In this guide
A borrowing base can limit usable funds below a facility's headline credit limit. Ask how the agreement defines eligible receivables, inventory, advance rates and deductions. A sales forecast is not automatically eligible collateral, and one lender's formula is not a universal standard.
Reconcile the certificate
Start with the underlying ledger, remove items the actual policy excludes, then apply the stated rates and deductions. Compare the result with outstanding borrowing and the facility limit. SBA's working-capital program highlights receivable aging, payable aging and inventory reporting as relevant monitored records; the actual offer sets the calculation.
Check how overdue invoices, customer concentration and unsold stock are handled. Do not move dates or reclassify inventory simply to improve availability. If accounting records change, ask how and when the lender needs updated reporting.
Stress-test shrinking eligibility
Model a customer paying late or inventory losing eligible status. The business may need cash even if total sales remain strong. Ask how shortfalls, notice and required reductions are handled in the agreement. A simplified worksheet helps anticipate a problem but does not replace the lender's accepted certificate or legal advice on collateral.
The relevant primary reference is SBA: current 7(a) program. Read its scope before applying it to a different lender or loan type.
A working checklist
| Record or question | Why it matters |
|---|---|
| Eligible balances | Separates collateral from total book value. |
| Contract advance rates | Uses the actual facility’s terms. |
| Deductions and outstanding draws | Reconciles remaining usable capacity. |
| Aging and stress changes | Tests availability when collection slows. |
A hypothetical case to work through
Assume hypothetical eligible receivables of $80,000 at a 75% advance rate and eligible inventory of $30,000 at 40%, with no other deductions. The illustrative base is $72,000. With $50,000 drawn, remaining base capacity is $22,000, even if the headline limit is $100,000. Rates and eligibility are invented, not SBA or lender standards.
Practical questions
Is the credit limit the same as the borrowing base? No. Both may constrain availability.
Can I use any receivable at the same advance rate? No. Use the agreement’s eligibility definitions and accepted reporting.
